Be it known that I, CLINTQN H.-FREN0H, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Sheet-- Holders for Music-Stands and the Like, of

which the following is a specification.

The object of the present invention is to provide a collapsible sheet holder for music stands and thelike, which shall be simple in construction and operation, and neat and key on a music stand, as is commonl attractive in appearance, occupy but small spacewhen collapsed, and provide a comparati'vely large extent of supporting surace.

In the accompanying drawing, Figure 1 is a'front view of the sheet holder collapsed; Fig. 2 is a rear. view of the same; Fig. 3 is a front view on a reduced scale of the holder extended; Fig. 4 is a similar view showing it partly extended; Fig. 5 is a rear broken view of the same Fig. 6 is a broken rear 4 view of the ends of the upper arms.

Referring to the drawing, 1 indicates the central stem of the holder, having-formed in its lower ortion a slot 2, and provided at the top on t e back, with a guide or loop 3. The upper end of said slot 2 tapers upwards, for the purpose of attachment to a ta ering uided in the loop 3 is a slidin rod 4, to the lower end of which is attacheda pin 5, which slides in the slot 2, and on which are pivoted, in

front of the central stem, arms 6, pivotally connected to links 7, which are themselves pivotally connected, as shown at 8, to the ulpper end of the stem. Upon moving the s 1 ing rod 4 downwards, so that the pin 5 slides downwards in the slot 2, the arms 6 and the links 7 are collapsed, and fold up in front of said central st'em.

Pivoted on the lower end of the stem as shown atv 11, are angular base plates 12, and likewise ivoted on said pivots 11 are arms 14, whic arms are ivotally connected, as

shown at 15, with lin s 16 alsoconnected to the pivot pm 5. It results that, upon depressing the slidin rod 4, the arms 14 and the links 16 are collapsed" behind the central stem. Pivotally'connected with said links 16 are toggle arms 17,, connected to pins 18 which move in slots 19 in the arms 14, said ins 18 being also connected by toggle arms 20 with the base plates 12. By reason of this construction, when the pin 5 descends Specification of ietters Patents. Application filed 1 m 25, 1907. Serial No. smite.

in the slot 2, the pinsl 'ar'e forced down-w wards 'or inwardsin theses; 19, "the effectbeing to draw the base plates inwards, so that, in the terminal position of the in 5 said base plates are collapsed behin and around the other parts of the device.

From the above description of the con-' struction the mode of operation will be readily understood. To open the sheet holder it is only necessary to draw upwards the slide rod 4. This moves the pin 5 in the slot 2, and causes the parts tospread and assume the osition shown inFig, 3. In like. manner al of the arts are colla "sed by pushing down the slid rod. For t e purpose of convehiently depressing said rod, its end'is bent forward to form a linger piece 22.

. It will be readily seen that the operation of the device is very simple; that when extended the arms assume such positions as to give a large extent of su porting surface,

evenly distributed; that t ere are no weak parts Where strength is required, and that I the device occupies but a small space when collapsed.

I claim v 1. Asheet holder comprising base plates, a central stem, a pin movably engagin said stem, upper arms ivoted u on sai pin, links ivoted to said arms an to the upper end of said stem, lower arms pivoted at the lower end of the stem, and links connected I to said arms and to said pin, substantially as f described. f

2. A sheet holder comprising av central stem, a pin movably engaging said stem, upper arms .pivoted upon said pin, links ivoted to said arms and to the upper en of said stem, lower arms pivoted at the lower end of the stem, links connected to said arms and to said in, base plates ivoted upon the lower on of the stem, an means actuated by the spreading of a pair of said arms for simultaneously s reading said plates, substantiall as descri ed. 3. A sheet hold .r comprising a central stem, a rod slidablethereon, a pin attached at the lower end ofv the 'rod and guided by the stem, -up er arms pivoted upon said pin, links ivoted to said arms and to the upper end 0 'said stem, lower arms pivoted at the lower end of the stem, links connected-to said arms and to said pin, and base plates pivoted upon the lower end of the stem substantially as described. 4. A sheet holder comprising a central stem, apin movably engaging said stem, an in the slots of said slotted arms, substanuppe'r pair of arms ivote upon said pin,- a tially as described. pair of links pivote to said arms and to the In testimony whereof I have hereunto set upper'end of the stem, a lower pair of slotted my hand in the presence of two subscribing .5 arms pivoted to the lower end of the stem, a wltnesses.
